40s Marked by the economic narrowness due to the war. Everything became more austere and fashion was no exception.
The woman began to work while her husbands were in the war. Some women enlisted as nurses to help the soldiers.
The waists were marked and the skirts were full of flight and without many ornaments. Gloves and headgear were used for day to day.
But now that is unlikely. People no longer wear hats unless it is winter and it is cold, much less wearing headdresses with hairnets to go shopping for them. We reserve that for weddings and other events.
Why not wear that style adapted to the current era? We can take an image of work without forgetting the elegance. Perhaps a headdress with a peacock feather is not the most appropriate for going on the subway but a pen shaped brooch on the wool cap is a more modest option.
Add a touch of elegance to your dresses and accessories. A simple dress can become a more elegant one by adding only a few buttons lined with fabric in contrast to the dress. Or an embroidered collar. And even some brooch of your grandmother or vintage style.
If you are more crafty and good seamstress you can add something more elaborate as a folds or a body of honeycomb as in the dress here below 40s. The lace is a simple and very feminine option.
As for accessories, the 40s cloches have become fashionable again and look great. You can have long or short hair, curly and smooth, that this will look great on you. With a simple dress you will give it a more elegant look.
